Hybridization and yield test of reciprocal watermelon in the greenhouse scale

\nThis study aims to select reciprocal watermelon crosses in a new superior variety breeding program using the single cross method. The male and female parents used in the study consisted of 12 pure lines (WM 08-19-1 ♂x♀ WM 06-27-4; WM 01-3-3-4-1 ♂x♀ WM 04-12-11-1-1; WM 11-1-2-2-8 ♂x♀ WM 10-1-1-9-10; WM 03-27-2 ♂x♀ WM 08-6-3; WM 12-1-5 ♂x♀ WM 04-1-5-10; WM 16-1-5-6-3 ♂x♀ WM 06-1-11-5). The study used a one-factor randomized block design (RBD) with 3 replications. Data analysis used analysis of variance and the least significant difference test (LSD) at the 5% level. The fastest harvest age was found in the WM 2110-1011 line and the fruit with the highest sweetness level was found in the WM 2110-1011 line. The results of the reciprocal hybridization research conducted, watermelon lines that have a plain striped type on the fruit are lines WM 06-27-4, WM 04-12-11-1-1 and WM 10-1-1-9-10. The thin striped type is found in the WM 08-6-3 line and the thick striped type is found in the 04-1-5-10 line and WM 06-1-11-5. The line that has yellow flesh is WM 04-1-5-10. The results of this study indicated that the collection of pure lines and reciprocal crosses are used as selection materials for the F1 hybrid watermelon breeding program.\n
